I’ve been working on a bait launcher with interchangeable barrels (1 1/2-inch, 2-inch, and 3-inch barrels) which can be fired from my fishing cart. It normally takes about 30-45 seconds to switch from one barrel to another. I used a Union Joint to attach the barrels to the front of the trigger/handle of the 2-inch valve. The big green handle is the trigger. I leave the Union Joint loose until after I place the molded ice projectile into the barrel which allows the trapped air in the barrel to escape as the projectile slides down the barrel. The Union Joint must be tightened prior to firing the bait cannon.
I use different size projectiles to suit the larger requirements for rigging as in shark fishing which includes 3-4 feet of piano wire along with a small cable along with the bait and weight. These are rolled into an elongated mass and placed in a 3-inch x 12-inch long bait mold made from 3-inch PVC pipe and rubber end caps used to seal them while they are freezing to keep from making a mess in the freezer. I am planning on trips to South Carolina and Florida for surf fishing in the next month. Hopefully, I will be able to post some video of the catches from the trips.
The ball valve is a Green Leaf 2 inch valve (Green Leaf 4 Bolt Ball Valve – 2”).
Tractor Supply Company ($29.99):
The diameter of the reservoir pipe is 4” and taking into account the 2” fittings to the valve and back end, the volume is 1.1 cubic feet give or take a cubic inch or two.
I use two barrels – a 2” and a 3”.
2” – 49 1/2” long including the male portion of the union fitting. There is a drain grid inside to keep any possible debris from falling into the valve putting the barrel length where the ice bullet rests at 49”.
3” – 49” long including the male portion of the union fitting. There is also a drain grid and a 2” reducer, etc. where the barrel attaches to the reservoir putting the barrel length where the ice bullet rests at 42 1/2”
